Researchers from the FOM Institute AMOLF and the University of Pennsylvania have fabricated a material which gives visible light a nearly infinite wavelength. The new metamaterial is made by stacking silver and silicon nitride ...

Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing. ...

Applications in imaging and sensing typically involve the emission of light at a different wavelength than the excitation, or "secondary light emission." The interpretation of resonant secondary light emission in terms of ...

The physical properties of the ultra-white scales on certain species of beetle could be used to make whiter paper, plastics and paints, while using far less material than is used in current manufacturing methods.

(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light in shorter pulses, ...

(Phys.org)—While today's smart phones, tablets, and other small electronic devices rely on electrical data connections, in the future they may use optical connections in order to become even faster and smaller. Photonic ...

Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances ...

(Phys.org) -- Replacing the need for nimble fingers, researchers have demonstrated how to make origami using light of a specific wavelength. They call the new folding technique photo-origami, and it could potentially be used ...

(Phys.org) —Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated ...
